Temporary circulatory support with surgically implanted microaxial pumps in postcardiotomy cardiogenic shock following coronary artery bypass surgery. JTCVS OPEN 2023; 15:252-260. [PMID: 37808068 PMCID: PMC10556953 DOI: 10.1016/j.xjon.2023.06.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 06/14/2023] [Accepted: 06/20/2023] [Indexed: 10/10/2023]
Abstract
Objectives Patients with ischemic cardiomyopathy undergoing coronary artery bypass grafting (CABG) surgery may develop postcardiotomy cardiogenic shock. In these cases, implantation of an Impella 5.0 or 5.5 microaxial pump offers full hemodynamic support while simultaneously unloading of the left ventricle. Methods Preoperative, perioperative, and postoperative data of all patients receiving postoperative support with an Impella 5.0 or 5.5 after CABG surgery between September 2017 and October 2022 were retrospectively collected. Cohort built-up was performed according to the timing of Impella implantation, either simultaneous during CABG surgery or delayed. Results A total of n = 42 patients received postoperative Impella support, of whom 27 patients underwent simultaneous Impella implantation during CABG surgery and 15 patients underwent delayed Impella therapy. Preoperative left ventricular ejection fraction was similarly low in both groups (26.7 ± 0.7% vs 24.8 ± 11.3%; P = .32). In the delayed cohort, Impella implantation was performed after a median of 1 (1; 2) days after CABG surgery. Survival after 30 days (75.6% vs 47.6%, P = .04) and 1 year (69.4% vs 29.8%, P = .03) was better in the cohort receiving simultaneous Impella implantation. Conclusions The combined advantages of hemodynamic support and LV unloading with microaxial pumps may lead to a favorable survival in patients with left ventricular failure following CABG surgery. Early implantation during the initial surgery shows a trend toward a more favorable survival as compared with patients receiving delayed support.

Vascular complications after peripheral veno-arterial extracorporeal life support cannulation in cardiogenic shock. IJC HEART & VASCULATURE 2023; 47:101230. [PMID: 37275625 PMCID: PMC10236458 DOI: 10.1016/j.ijcha.2023.101230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 05/16/2023] [Accepted: 05/21/2023] [Indexed: 06/07/2023]
Abstract
Background Extra Corporeal Life Support (ECLS) is an evolving therapy in therapy-resistant cardiogenic shock (CS). Vascular cannulation in emergency situations can be accomplished through puncture of the femoral vessels by specialised teams. Since lower limb ischemia constitutes one of the major complications following cannulation, a distal perfusion cannula (DPC) has emerged as standard of care. We here aimed to analyse the impact of the DPC on limb perfusion and 6-month survival rate. Methods In a retrospective study from January 2012 to December 2018, 98 patients with cardiogenic shock and peripheral (v-a) ECLS implantation with documented limb perfusion status were identified and analysed. Demographic data, laboratory parameters, cause of CS, comorbidities, limb perfusion complications and complication management were analysed. Results 53 patients (54%) received ECLS therapy in referral centers by our mobile ECLS team, while in 45 patients (46%) the cannulation occured in our center. 71 patients (72%) received a DPC (group A) at the time of ECLS implantation, whereas 27 (28%) (group B) did not or received later (14 patients owing to limb ischemia). 44 patients (45%) developed limb ischemia as a complication of ECLS therapy (31% in group A and 81% in group B- p < 0.001). The 6-month survival rate was 28% in our study cohort (30% in group A and 22% in group B- p = 0.469). Conclusion Lower limb ischemia remains a serious complication after peripheral ECLS cannulation in CS, especially when a DPC is absent. Standardised DPC implementation may reduce the rate of severe limb complications in peripheral ECLS.

Improvements in Extracorporeal Membrane Oxygenation for Primary Graft Failure After Heart Transplant. Ann Thorac Surg 2023; 115:751-757. [PMID: 35430222 DOI: 10.1016/j.athoracsur.2022.03.065] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 02/21/2022] [Accepted: 03/28/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Severe primary graft failure is a life-threatening complication of heart transplantation that may require venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Surgical practices and management strategies regarding VA-ECMO vary between and within centers. METHODS We performed a single-center retrospective cohort study on adult patients who received VA-ECMO for primary graft failure between 2013 and 2020. Clinical data were obtained from chart review and national databases. Patients were stratified by transplantation before or after 2017, when our center adopted additional objective criteria for VA-ECMO, adopted partial-flow support, and changed from central cannulation to chimney graft arterial cannulation of brachiocephalic, axillary, or aorta. The primary outcome was survival to device weaning. Secondary outcomes were survival to discharge, survival to 1 year, complications on support, and time to sedation weaning and extubation. RESULTS From 276 heart transplant recipients, 39 severe primary graft failure patients requiring VA-ECMO were identified. Incidence of graft failure was 13% (n = 18 of 135) pre-2017 and 15% (n = 21 of 141) post-2017. Survival at all time points improved significantly after 2017, with greatest difference in survival to device weaning (61% pre-2017 vs 100% post-2017). After controlling for other factors in multivariable Cox regression modeling, transplantation after 2017 was a predictor of reduced mortality (hazard ratio, 0.209; 95% CI, 0.06-0.71; P = .01). Significant differences were not observed in other secondary outcomes of recovery. CONCLUSIONS The new VA-ECMO strategy displayed reasonable survival and a remarkable improvement from the prior system.

Cannulation-related adverse events of peripheral veno-arterial extracorporeal membrane oxygenation support in heart transplantation: Axillary versus femoral artery cannulation. Clin Transplant 2023; 37:e14871. [PMID: 36468757 DOI: 10.1111/ctr.14871] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 11/14/2022] [Accepted: 11/24/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND In heart transplantation (HT), peripheral veno-arterial extracorporeal membranous oxygenation (VA-ECMO) is utilized preoperatively as a direct bridge to HT or postoperatively for primary graft dysfunction (PGD). Little is known about wound complications of an arterial VA-ECMO cannulation site which can be fatal. METHODS From 2009 to 2021, outcomes of 80 HT recipients who were supported with peripheral VA-ECMO either preoperatively or postoperatively were compared based on the site of arterial cannulation: axillary (AX: N = 49) versus femoral artery (FA: N = 31). RESULTS Patients in the AX group were older (AX: 59 years vs. 52 years, p = .006), and less likely to have extracorporeal cardiopulmonary resuscitation (0% vs. 12.9%, p = .040). Survival to discharge (AX, 81.6% vs. FA. 90.3%, p = .460), incidence of stroke (10.2% vs. 6.5%, p = .863), VA-ECMO cannulation-related bleeding (6.1% vs. 12.9%, p = .522), and arm or limb ischemia (0% vs. 3.2%, p = .816) were comparable. ECMO cannulation-related wound complications were lower in the AX group (AX, 4.1% vs. FA, 45.2%, p < .001) including the wound infections (2.0% vs. 32.3%, p < .001). In FA group, all organisms were gram-negative species. In univariate logistic regression analysis, AX cannulation was associated with less ECMO cannulation-related wound complications (Odds ratio, .23, p < .001). There was no difference between cutdown and percutaneous FA insertion regarding cannulation-related complications. CONCLUSIONS Given the lower rate of wound complications and comparable hospital outcomes with femoral cannulation, axillary VA-ECMO may be an excellent option in HT candidates or recipients when possible.

Abstract
Objective To investigate the preventive effect of distal perfusion catheters (DPCs) on vascular complications in patients undergoing venous artery extracorporeal membrane oxygenation (VA-ECMO). Methods Patients who underwent VA-ECMO through a femoral approach in our hospital were included in this study, and they were divided into two groups according to their use of DPC. Clinical indicators were compared between the two groups, including the ECMO running time, intensive care unit (ICU) time, length of hospital stay, ECMO auxiliary results, the incidence of limb ischemia and vascular complications. Results In total, 250 patients were included in this study, including the DPC group (age: 48 [32-62] years old, 58.4% male, n = 125) and the non-DPC group (age: 51 [36-63] years old, 65.6% male, n = 125). The DPC group was less likely to have limb complications than the non-DPC group (6.4% vs 17.6%, P = 0.006), mainly resulting from distal ischemia (4.0% vs 15.2%, P = 0.003) and necrosis (1.6% vs 9.6%, P = 0.006). The ECMO duration had a median of 92.3 (75.7-109) h in the DPC group and 71.2 (59.4-82.8) h in the DPC group, with a difference close to the statistical threshold (P = 0.054). There was no significant difference in ICU time or length of hospital stay between the two groups. The multivariate analysis showed that the DPC implantation was negatively associated with limb complications (odds ratio: 0.265, 95% confidence interval: 0.107-0.657, P = 0.004) after adjustment for confounding factors. Conclusion Distal perfusion catheter placement might be associated with a decreased risk of vascular complications and limb ischemia in patients undergoing femoral VA-ECMO cannulation. Further randomised studies are still needed to verify its benefit on clinical outcomes.

Abstract
INTRODUCTION The axillary artery is a reliable inflow vessel when addressing pathology of the aortic root and aortic arch that may preclude standard central cannulation strategies. This narrative review examines the use of the axillary artery in cardiac surgery. Anatomy, indications for use, cannulation strategies, and potential complications will be discussed. METHODS A comprehensive review of the current literature was performed using PubMed, Cochrane Review, and authoritative committee guidelines. A narrative review incorporating current available evidence was undertaken. COMMENT Use of the axillary artery in select cardiac surgical cases is reliable, reproducible, and may be preferable in certain cases involving ascending aortic pathology, reoperative surgery, porcelain aorta, access for transcatheter valve therapies, and peripheral mechanical circulatory support.

Direct Axillary Artery Cannulation for Aortic Surgery: Lessons From Contemporary Experiences. Ann Thorac Surg 2022; 114:1341-1347. [PMID: 35292261 DOI: 10.1016/j.athoracsur.2022.02.048] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/14/2022] [Accepted: 02/09/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND This study seeks to assess the outcomes of direct axillary artery (AX) cannulation for thoracic aortic surgery. METHODS From October 2009 to November 2021 direct AX cannulation was planned in 515 patients for thoracic aortic pathology. An important aspect of our technique is that the cannula is not inserted deeper than 3 cm. AX cannulation-related events included shift of cannulation site from the initial site, vascular injury, and iatrogenic dissection. RESULTS Half of the patients had acute type A dissection (ATAD). An angled cannula was used in 442 patients and a straight cannula in 73 patients (14.2%) after August 2020. A previously cannulated AX was reused in 36 patients (7.0%). Mortality and stroke rates were 5.4% (ATAD vs non-ATAD: 8.0% vs 2.8%, P = .008) and 2.7% (ATAD vs non-ATAD: 4.6% vs 0.8%, P = .034), respectively. AX cannulation-related events were observed in 2.7% of patients. There was no difference in the vascular injury rate between ATAD and non-ATAD cases (1.6% vs 0.4%, respectively; P = .385), between different cannula types (angled vs straight: 0.9% vs 1.4%, P = 1.00), or between primary and redo AX cannulation cases (0.8% vs 2.8%, respectively; P = .791). On multidetector computed tomography analysis using automated 3-dimensional images, the mean distance from the thoracoacromial artery to the vertebral artery on the right and left sides was 8.70 cm and 8.69 cm, respectively. CONCLUSIONS Direct AX cannulation for thoracic aortic repair is safe and carries a low rate of vascular injury, especially in elective cases. Our direct cannulation technique, which includes not inserting a cannula deeper than 3 cm, seems to be safe in not occluding the vertebral artery.

Abstract
BACKGROUND With increasing extracorporeal membrane oxygenation (ECMO) utilization over the last decade, clinicians have developed "hybrid" configurations to meet complex perfusion requirements. In the setting of differential hypoxemia, a veno-arteriovenous (V-AV) configuration provides oxygenated cardiac preload and hemodynamic support to satisfy physiologic demands. We aim to further characterize the patient population, indications, and outcomes associated with this hybrid configuration. METHODS We retrospectively reviewed all adult patients placed on V-AV ECMO at our institution from June 2016 to December 2019. Through a review of the electronic medical records, data describing demographic features, comorbidities, and ECMO-specific information were analyzed systematically. RESULTS 14 patients were placed on V-AV ECMO during the study period. Our cohort was 79% male with a median age of 54 and BMI of 30.3. These patients had a median SOFA-0 score of 15 and SAVE score of -12. Patients were treated with ECMO support for a median of 144.1 (IQR 98.5 - 183.1) hours, consisting of 0.2 (IQR 0 - 17.7) hours of VA and 92.4 (IQR 53.7 - 115.1) hours of V-AV followed by 67.4 (IQR 20.3 - 96.6) hours of VV support. Of these 14 patients, 11 survived to decannulation (79%) and 9 survived to hospital discharge (64%). CONCLUSION ECMO patients with recovering left ventricular function and persistent gas exchange abnormalities are at risk for developing differential hypoxemia. We describe an approach to utilizing V-AV configuration when the likelihood of differential hypoxemia is extremely high, with a survival rate that compares favorably to Extracorporeal Life Support Organization statistics and published case series.

Abstract
BACKGROUND Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) has been used as a bridge to lung transplantation with acceptable outcomes. We hypothesized that VA ECMO, as part of a multidisciplinary ECMO program, yields similar outcomes as VV ECMO as a bridge in lung transplantation. METHODS Records of all patients who had undergone ECMO with the intention to bridge to lung transplantation at University of California Los Angeles from January 1, 2012 to March 31, 2020 were reviewed. Baseline characteristics, in-hospital outcomes, long-term survival, and freedom from bronchiolitis obliterans syndrome (BOS) were assessed. RESULTS During this interval, 58 patients were placed on ECMO with the intention to bridge to lung transplantation: 27 on VV ECMO, and 31 on VA ECMO with a median duration of 7 and 17 days of support, respectively(p=0.01). Successful bridge to lung transplantation occurred in 21(78%) VV and 26(84%) VA patients. Incidence of primary graft dysfunction III(PGD III) at 72 hours in the VV and the VA cohorts were 0% and 4%, respectively(p=0.99). In-hospital and 90-day survival of the VV and VA groups were 100% and 96%, respectively(p=0.99). Three-year survival of the two groups were not significantly different from a contemporary cohort of lung transplant recipients not bridged with ECMO. CONCLUSIONS VA and VV ECMO can both be used as a bridge to lung transplantation with high success, with short and medium-term survival similar to non-bridged lung transplant recipients. Both modes should be considered effective at bridging select candidates to lung transplantation.

Abstract
OBJECTIVE To assess the influence of primary arterial access in patients receiving peripheral postcardiotomy extracorporeal life support on associated complications and outcome. METHODS Of 573 consecutive patients requiring PC-ECLS between 2000 and 2019 at a single center, 436 were included in a retrospective analysis and grouped according to primary arterial extracorporeal life support access site. Survival and rate of access-site-related complications with special emphasis on fatal/disabling stroke were compared. RESULTS The axillary artery was cannulated in 250 patients (57.3%), whereas the femoral artery was used as primary arterial access in 186 patients (42.6%). There was no significant difference in 30-day (axillary: 62%; femoral: 64.7%; P = .561) and 1-year survival (axillary: 42.5%; femoral: 44.8%; P = .657). Cerebral computed tomography-confirmed stroke with a modified ranking scale ≥4 was significantly more frequent in the axillary group (axillary: n = 28, 11.2%; femoral: n = 4, 2.2%; P = .0003). Stroke localization was right hemispheric (n = 20; 62.5%); left hemispheric (n = 5; 15.6%), bilateral (n = 5; 15.6%), or infratentorial (n = 2; 6.25%). Although no difference in major cannulation site bleeding was observed, cannulation site change for bleeding was more frequent in the axillary group (axillary: n = 13; 5.2%; femoral: n = 2; 1.1%; P = .03). Clinically apparent limb ischemia was significantly more frequent in the femoral group (axillary: n = 12, 4.8%; femoral: n = 31, 16.7%; P < .0001). CONCLUSIONS Although survival did not differ, surgeons should be aware of access-site-specific complications when choosing peripheral PC-ECLS access. Although lower rates of limb ischemia and the advantage of antegrade flow seem beneficial for axillary cannulation, the high incidence of right hemispheric strokes in axillary artery cannulation should be considered.

Abstract
Legionella pneumophila is a common cause of community- and hospital-acquired pneumonia. Its increasing frequency and reemergence as a pathogen of interest in the intensive care unit is likely due to increased awareness, recognition, and diagnostic test availability (1). Extracorporeal Membrane Oxygenation (ECMO) is increasingly used in the pediatric intensive care unit (PICU) for refractory cardiopulmonary failure and acute respiratory distress syndrome (ARDS) in concert with conventional modalities or when these have failed to adequately support the patient. The breadth of applications for this technology are ever-expanding as our collective knowledge and experience grows. With a particularly high mortality rate among immunocompromised patients, Legionnaires' disease should be considered early in the differential diagnosis and appropriate antimicrobials initiated (1). We present the case of an adolescent patient with pre-B-cell acute lymphoblastic leukemia (pre-B ALL) requiring ECMO support for septic shock and ARDS due to disseminated Legionella. To our knowledge, this is the first case describing an immunocompromised pediatric patient supported with ECMO for Legionnaires' disease.

Abstract
Ambulatory extracorporeal membrane oxygenation (ECMO) has shown promise as a bridge to lung transplantation. The primary goal of ambulatory ECMO is to provide enough gas exchange to allow patients to participate in preoperative physical therapy. Various strategies of ambulatory ECMO are utilized depending upon patients’ need. A wide spectrum of ECMO configurations is available to tackle this situation. We discuss those configurations in this article.

Postcardiotomy Veno-Arterial Extracorporeal Membrane Oxygenation: Does the Cannulation Technique Influence the Outcome? Front Cardiovasc Med 2021; 8:658412. [PMID: 34434969 PMCID: PMC8382236 DOI: 10.3389/fcvm.2021.658412] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 06/23/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) may be cannulated using either central (cannulation of aorta) or peripheral (cannulation of femoral or axillary artery) access. The ideal cannulation approach for postcardiotomy cardiogenic shock (PCS) is still unknown. The aim of this study is to compare the outcome of patients with PCS who were supported with central vs. peripheral cannulation. Methods: This is a single-center retrospective data analysis including all VA-ECMO implantations for PCS from January 2011 to December 2017. The central and peripheral approaches were compared in terms of patient characteristics, intensive care unit (ICU) stay, hospitalization length, adverse event rates, and overall survival. Results: Eighty-six patients met the inclusion criteria. Twenty-eight patients (33%) were cannulated using the central approach, and 58 patients (67%) were cannulated using the peripheral approach. Forty-three patients (50%) received VA-ECMO in the operating room and 43 patients (50%) received VA-ECMO in the ICU. Central VA-ECMO group had higher EuroSCORE II (p = 0.007), longer cross-clamp time (p = 0.054), higher rate of open chest after the procedure (p < 0.001), and higher mortality rate (p = 0.02). After propensity score matching, 20 patients in each group were reanalyzed. In the matched groups, no statistically significant differences were observed in the baseline characteristics between the two groups except for a higher rate of open chests in the central ECMO group (p = 0.02). However, no significant differences were observed in the outcome and complications between the groups. Conclusions: This study showed that in postcardiotomy patients requiring VA-ECMO support, similar complication rates and outcome were observed regardless of the cannulation strategy.

Abstract
Extracorporeal life support (ECLS), also known as extracorporeal membrane oxygenation (ECMO), increasingly is used in postcardiotomy (PC) shock to facilitate a bridge to sustained recovery, long-term mechanical support, or heart transplantation. Given increasing prevalence and complexity of PC-ECLS, a joint expert consensus guideline was created in 2020 for management of adult PC-ECLS by the European Association for Cardio-Thoracic Surgery (EACTS), the Extracorporeal Life Support Organization (ELSO), the Society of Thoracic Surgeons (STS), and the American Association of Thoracic Surgery (AATS). The aim of this analysis was to comprehensively review the expert consensus guidelines, with particular emphasis on PC-ECLS candidacy, timing, cannula configuration, left ventricular distention, anticoagulation, ECLS weaning, and intensive care unit complications. This analysis finds the expert consensus guideline to be timely, pertinent, and clinically valuable, although there remains the need for larger clinical trials to codify best practices.

Abstract
Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an effective means of support for patients awaiting cardiac or cardiopulmonary transplantation. Typically, peripheral cannulation via the femoral vessels is preferred. However, an alternative is use of the axillary or subclavian artery, which is typically performed via a graft. Here we present the case of a patient who required VA-ECMO for cardiogenic shock with severe pulmonary hypertension as a bridge to heart-lung transplantation. Initially cannulated via the femoral artery, he was converted to a direct axillary cannulation strategy with a distal perfusion catheter and successfully bridged to transplantation. This technique avoids the use of an interposition graft and mitigates problems associated with it.

Abstract
OBJECTIVES Perform a systematic review and meta-analysis of vascular complications associated with extracorporeal membrane oxygenation and identify prognostic and predictive factors. DATA SOURCES Systematic search for publications reporting vascular complications on extracorporeal membrane oxygenation, published from 1972 to January 31, 2020, was conducted via PubMed, Scopus, and Embase. STUDY SELECTION Of 4,076 references screened, 47 studies with 6,583 patients were included in final analyses. Studies with fewer than 10 patients were excluded. DATA EXTRACTION Relevant data, including demographics, comorbidities, extracorporeal membrane oxygenation and cannulation characteristics, occurrence rates of early and late vascular complications, patient outcomes, and use of distal perfusion cannula, were extracted from selected articles into an excel sheet specifically designed for this review. DATA SYNTHESIS Random-effects meta-analyses and meta-regression analyses were undertaken. Overall pooled estimate of vascular complications in our meta-analysis was 29.5% (95% CI, 23.6-35.9%). Two-thousand three-hundred forty-seven vascular complications in 6,124 venoarterial extracorporeal membrane oxygenation patients compared with 95 in 459 venovenous extracorporeal membrane oxygenation patients (odds ratio, 2.35; 95% CI, 1.87-2.96; p < 0.0001) were analyzed. Successful weaning off extracorporeal membrane oxygenation occurred in 60.6% of pooled patients; 46.2% were eventually discharged. Pooled prevalences of vascular complications like significant bleeding, limb ischemia, and cannula site bleeding were 15.4% (95% CI, 8.6-23.7%), 12.6% (95% CI, 10.0-15.5%), and 12.6% (95% CI, 9.6-18.5%), respectively. Meta-analysis showed that the use of distal perfusion cannula was associated with lower odds of limb ischemia (odds ratio, 1.93; 95% CI, 1.17-2.47; p = 0.03) Meta-regression showed that male sex, smoking, advanced age, and comorbidities contributed to higher in-hospital mortality, while distal perfusion cannula was protective. CONCLUSIONS Nearly a third of patients on extracorporeal membrane oxygenation develop vascular complications; elderly males with comorbidities appear vulnerable. The use of distal perfusion cannulas caused significant reduction in limb ischemia and mortality.

Abstract
Post-cardiotomy extracorporeal life support (PC-ECLS) in adult patients has been used only rarely but recent data have shown a remarkable increase in its use, almost certainly due to improved technology, ease of management, growing familiarity with its capability and decreased costs. Trends in worldwide in-hospital survival, however, rather than improving, have shown a decline in some experiences, likely due to increased use in more complex, critically ill patients rather than to suboptimal management. Nevertheless, PC-ECLS is proving to be a valuable resource for temporary cardiocirculatory and respiratory support in patients who would otherwise most likely die. Because a comprehensive review of PC-ECLS might be of use for the practitioner, and possibly improve patient management in this setting, the authors have attempted to create a concise, comprehensive and relevant analysis of all aspects related to PC-ECLS, with a particular emphasis on indications, technique, management and avoidance of complications, appraisal of new approaches and ethics, education and training.

Abstract
Mechanical circulatory support (MCS) devices, especially veno-arterial extracorporeal membrane oxygenation (VA-ECMO) devices, are increasingly used to shore complex cardiac procedures in high-risk patients. We are reporting two cases where patients underwent coronary artery bypass grafting (CABG) under support of VA-ECMO in the setting of cardiogenic shock complicating acute myocardial infarction. The patients had different courses, but both survived the initial insult and were weaned successively from VA-ECMO. Our report indicates that VA-ECMO can be used instead of the cardiopulmonary bypass machine (CPB) to support the circulation during CABG surgery in patients with complex coronary anatomy and unstable haemodynamics. Future studies focusing on the long-term outcomes of such patients will probably help to establish the optimal management of this type of patients.

Abstract
Abstract
OBJECTIVES
Our goal was to assess the safety, outcomes and complication rate of axillary artery cannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO).
METHODS
A retrospective analysis was conducted on data obtained from the review of medical charts of all consecutive patients undergoing VA-ECMO implantation between January 2013 and December 2017 at a teaching hospital. Only patients with right axillary VA-ECMO implantation in a non-emergency setting were included. Post-procedural outcomes and local and systemic complications were analysed.
RESULTS
One hundred and seventy-four [131 male (75.3%), 43 female (24.7%); mean age 56.8 ± 15.1 years] patients underwent femoral-axillary VA-ECMO. Indications were cardiogenic shock from any cause (n = 78, 44.8%) or post-cardiotomy syndrome (n = 96, 55.2%). Fifty-three (30.5%) patients died while on VA-ECMO support. At the time of VA-ECMO ablation, 89 (51.1%) patients had recovered; 13 (7.5%) patients were bridged to a long-term mechanical support device and 19 (10.9%) patients underwent heart transplants. Thirty-day and 1-year mortality was 36.2% (n = 63) and 49.4% (n = 86), respectively. The 1-year survival rate of patients who were weaned from VA-ECMO support was 72.7% (n = 88). The complications of axillary cannulation were bleeding (n = 7, 4%), local infection (n = 3, 1.7%), upper limb ischaemia (n = 2, 1.1%) and brachial plexus injury (n = 1, 0.6%). Left ventricle unloading was required for 9 (5.2%) patients. The median duration of VA-ECMO support was 7 (range 1–26) days.
CONCLUSIONS
Right axillary artery cannulation is a safe and reliable method for VA-ECMO support with a low rate of local complications. In the absence of a control group with femoro-femoral cannulation, no definitive conclusion about the superiority of axillary over femoral cannulation can be drawn.

Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) has become an accepted treatment modality in the management of select patients with cardiopulmonary failure. As a result, its use has increased significantly over the past decade. However, the effect of complications on mortality is not clearly established. We performed a comprehensive, up-to-date meta-analysis of peer-reviewed literature focusing on the effect of vascular complications (VCs) on the survival of patients receiving venoarterial ECMO (VA-ECMO) with femoral cannulation. METHODS A systematic search of 4 different databases (PubMed, Embase, Scopus, and Web of Science) was conducted from their inception to mid-September of 2019. To keep the pooled analysis current, only studies published within the past 5 years were included. Mortality was analyzed based on presence or absence of VCs. Studies with less then 10 patients, with incomplete mortality data, and not accessible in the English language were excluded. RESULTS Ten studies were included in the analysis encompassing 1,643 patients over a 5-year period. There were 369 patients with a cumulative VC rate of 22.5% (range 9.4 to 43.9%). The pooled mortality rate for patients with and without VCs was 69.6% and 56.8%, respectively. Meta-analysis demonstrated a significant correlation between VCs and mortality with a relative risk (RR) of 1.36 (95% confidence interval (CI), 1.15-1.60; P = 0.0004). Covariate-adjusted meta-regression analysis revealed an inverse relationship between age and mortality for VCs, with an RR of 1.33 (95% CI, 1.15-1.54; P = 0.0184), and direct relationship between female gender and mortality from VCs, RR 1.39 (95% CI, 1.21-1.59; P = 0.0165). CONCLUSIONS The most recently available data published in the literature demonstrate a significant correlation of VCs with mortality. Therefore, aggressive attempts should be made to minimize VCs in patients with femoral VA-ECMO cannulation.

Abstract
Objective To review the outcomes of axillary artery (AX) and femoral artery (FA) cannulation for veno-arterial extracorporeal membraneous oxygenation (VA-ECMO). Methods From 2009 to 2019, 371 patients who were supported with VA-ECMO for cardiogenic shock were compared based on the arterial cannulation site: AX (n = 218) versus FA (n = 153). Results Patients in the AX group were older (61 years vs 58 years, P = .011), had a greater prevalence of peripheral vascular disease (13.8% vs 5.2%, P = .008), and were less likely to have undergone cardiopulmonary resuscitation preoperatively (18.8% vs 36.6%, P < .001). Other characteristics were similar between groups, as were in-hospital outcomes, including survival to discharge (60.6% vs 56.9%), cerebrovascular accidents (12.4% vs 10.5%), cannulation-related bleeding (15.1% vs 17%), and length of VA-ECMO support (6 days). The incidence of leg ischemia (6.9% vs 15.7%, P = .006), limb ischemia related to VA-ECMO cannulation (0% vs 10.5%), the need to switch the cannulation site (4.6% vs 14.7%), and wound complications (WCs; 2.8% vs 15%) including infection and additional procedure were significantly greater in the FA group (P < .001). In multiple logistic regression analysis, FA cannulation and primary graft failure after heart transplantation were independent risk factors for cannulation-related WC. In subgroup analysis among patients with primary graft failure, WCs were more prevalent in FA cannulation (3.6% vs 39.1%, P = .001). Conclusions AX cannulation for VA-ECMO is a safe and effective alternative to FA cannulation. It can be considered especially for patients with limited groin access, peripheral vascular disease, or for primary graft failure after heart transplant.

Abstract
Lower extremity ischemic complications are frequently encountered after femoral cannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO). Many are attributed to mechanical obstruction of distal arterial blood flow related to intraluminal positioning of the arterial cannula. Routine use of distal perfusion catheters is ineffective at eliminating the development of these serious complications. Side- arm grafting instead of direct arterial cannulation is suggested as an alternative. Here, the authors present a case wherein a patient developed suspected lower extremity ischemia from hyperperfusion after femoral VA-ECMO cannulation during use of an arterial side- arm graft, calling into question the benefits of this cannulation strategy.

Abstract
BACKGROUND Cardiogenic shock (CS) is a state of critical end-organ hypoperfusion due to a primary cardiac disorder. For people with refractory CS despite maximal vasopressors, inotropic support and intra-aortic balloon pump, mortality approaches 100%. Mechanical assist devices provide mechanical circulatory support (MCS) which has the ability to maintain vital organ perfusion, to unload the failing ventricle thus reduce intracardiac filling pressures which reduces pulmonary congestion, myocardial wall stress and myocardial oxygen consumption. This has been hypothesised to allow time for myocardial recovery (bridge to recovery) or allow time to come to a decision as to whether the person is a candidate for a longer-term ventricular assist device (VAD) either as a bridge to heart transplantation or as a destination therapy with a long-term VAD. OBJECTIVES To assess whether mechanical assist devices improve survival in people with acute cardiogenic shock. SEARCH METHODS We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid) and Web of Science Core Collection in November 2019. In addition, we searched three trials registers in August 2019. We scanned reference lists and contacted experts in the field to obtain further information. There were no language restrictions. SELECTION CRITERIA Randomised controlled trials on people with acute CS comparing mechanical assist devices with best current intensive care management, including intra-aortic balloon pump and inotropic support. DATA COLLECTION AND ANALYSIS We performed data collection and analysis according to the published protocol. Primary outcomes were survival to discharge, 30 days, 1 year and secondary outcomes included, quality of life, major adverse cardiovascular events (30 days/end of follow-up), dialysis-dependent (30 days/end of follow-up), length of hospital stay and length of intensive care unit stay and major adverse events. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of a body of evidence as it relates to the studies which contribute data to the meta-analyses for the prespecified outcomes Summary statistics for the primary endpoints were risk ratios (RR), hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs). MAIN RESULTS The search identified five studies from 4534 original citations reviewed. Two studies included acute CS of all causes randomised to treatment using TandemHeart percutaneous VAD and three studies included people with CS secondary to acute myocardial infarction who were randomised to Impella CP or best medical management. Meta-analysis was performed only to assess the 30-day survival as there were insufficient data to perform any further meta-analyses. The results from the five studies with 162 participants showed mechanical assist devices may have little or no effect on 30-day survival (RR of 1.01 95% CI 0.76 to 1.35) but the evidence is very uncertain. Complications such as sepsis, thromboembolic phenomena, bleeding and major adverse cardiovascular events were not infrequent in both the MAD and control group across the studies, but these could not be pooled due to inconsistencies in adverse event definitions and reporting. We identified four randomised control trials assessing mechanical assist devices in acute CS that are currently ongoing. AUTHORS' CONCLUSIONS There is no evidence from this review of a benefit from MCS in improving survival for people with acute CS. Further use of the technology, risk stratification and optimising the use protocols have been highlighted as potential reasons for lack of benefit and are being addressed in the current ongoing clinical trials.

Abstract
Lung transplantation is the gold standard for treating patients with end-stage lung disease. Such patients can present with severe illness on the waitlist and may deteriorate before a lung donor is available. Bridging strategies with extracorporeal membrane oxygenation (ECMO) are valuable for getting patients to transplant and provide a chance at survival. The current article describes the indications, contraindications, and techniques involved in bridging to lung transplantation with ECMO.

Abstract
Each cannulation strategy for venoarterial extracorporeal membrane oxygenation (VA ECMO) has distinct benefits and drawbacks. In this article, various cannulation strategies including their indications are discussed. The gold standard for cannulation involves peripheral, percutaneous double cannulation utilizing the patient's femoral vein and artery. In emergency situations under mechanical resuscitation, a simple and fast cannulation technique is crucial to reestablish circulation. This is usually performed percutaneously utilizing the femoral approach. However, in cases of anticipated long-term support, such as while awaiting cardiac transplantation, more sophisticated cannulation techniques (e.g., internal jugular vein to left axillary artery, left axillary artery for neuroprotection) are necessary to facilitate mobilization and physical conditioning on VA ECMO. More complicated are cases involving combined respiratory and cardiac failure requiring dual organ support or triple cannulation with an additional venous return cannula resulting in a veno-arterio-venous (VAV) configuration. Cases with left ventricular stasis with need for unloading are also highly demanding. Unloading the left ventricle (LV) can be performed in numerous ways, described elsewhere in this issue. However, one particular mode of unloading the LV is described as a stepwise and cost saving bridge to a durable paracorporeal left ventricular assist device in patients with an uncertain prognosis, which involves implantation of Berlin Heart® EXCOR cannulas with temporary right heart support as an example of quadruple cannulation.

Abstract
Background Peripheral ECMO is an effective cardiopulmonary support in clinical. The perfusion level could directly influence the performances and complications. However, there are few studies on the effects of the perfusion level on hemodynamics of peripheral ECMO. Methods The geometric model of cardiovascular system with peripheral ECMO was established. The blood assist index was used to classify the perfusion level of the ECMO. The flow pattern from the aorta to the femoral artery and their branches, blood flow rate from aorta to brain and limbs, flow interface, harmonic index of blood flow, wall shear stress and oscillatory shear index were chosen to evaluate the hemodynamic effects of peripheral ECMO. Results The results demonstrated that the flow rate of aorta outlets increased and perfusion condition had been improved. And the average flow to the upper limbs and brain has a positive correlation with BAI (r = 0.037, p < 0.05), while there is a negative correlation with lower limbs (r = − 0.054, p < 0.05). The HI has negative correlation with BAI (p < 0.05, r < 0). The blood interface is further from the heart with the BAI decrease. And the average WSS has negative correlation with BAI (p < 0.05, r = − 0.983) at the bifurcation of femoral aorta and has positive correlation with BAI (p < 0.05, r = 0.99) at the inner aorta. The OSI under different BAI is higher (reaching 0.4) at the inner wall of the aortic arch, the descending aorta and the femoral access. Conclusions The pathogenesis of peripheral ECMO with different perfusion levels varies; its further research will be thorough and extensive.

Abstract
Venoarterial extracorporeal membrane oxygenation (ECMO) can provide temporary cardiopulmonary support for patients in hemodynamic extremis or refractory heart failure until more durable therapies-such as cardiac transplantation or a left ventricular assist device-can be safely implemented. Conventional ECMO cannulation strategies commonly employ the femoral artery and vein, constraining the patients to the supine position for the duration of ECMO support. We have recently adopted a modified cannulation approach to promote patient mobility, rehabilitation, and faster recovery and to mitigate complications associated with femoral arterial cannulation, such as limb ischemia and compartment syndrome. This technique involves cannulation of the subclavian artery and vein. The current case report details our recent experience with this approach in a critically ill patient awaiting cardiac transplantation.

Abstract
Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are an increasingly established advanced therapy for emerging severe lung and/or cardiocirculatory dysfunction or failure. Several reports have provided evidence for a potential benefit in prognosis by ECLS in cases of cardiogenic shock including cardiopulmonary resuscitation. Routine use in specialized centers reduces the incidence of negative side effects (e.g., vascular/ischemic, embolic, hemorrhagic, hemolytic and, furthermore, septic). Vascular complications like not only limb ischemia but also hypoxia proximal to the cannulation site up to complete sectorial hypoxia called "harlequin phenomenon" could refer to be a major adverse event in ECLS which, therefore, should be limited primarily to cardiocirculatory indications. Here we report on a case with "harlequin phenomenon" after ECLS implementation as a relevant complication of the mode of cannulation and review benefits and risks of commonly used variants of vascular access.

Abstract
Objective Axillary artery cannulation is still regarded with distrust by surgeons because the artery is supposed to be fragile, difficult to access, and its cannulation is often considered time-consuming. This study was carried out to assess our results in a series of patients, using a simplified surgical approach to axillary artery cannulation. Methods Data were collected retrospectively from our prospective database. All patients operated on in our department between January 2004 and October 2016 and scheduled for various cardiac procedures with direct axillary artery cannulation were included in this study. In this twelve-year period, 246 patients had direct axillary artery cannulation during a cardiac surgical procedure. The mean age was 67.3 ± 14.7 years. The artery was approached at the level of the deltopectoral groove and cannulated by the direct Seldinger technique. Results The main indications for axillary artery cannulation were: right minithoracotomy aortic valve replacement ( n = 93), aortic dissection ( n = 57), extracorporeal life support ( n = 36), transarterial valve replacement ( n = 27), ascending aortic aneurysm ( n = 16), and others ( n = 17). The cannulation was right-sided in 90.6% of patients. Axillary cannulation-related morbidity was 6.1%. Axillary cannulation-related mortality was 0.8% (2 patients). Conclusions The axillary artery is a reliable site for rapid cannulation, carrying a low risk of morbidity and mortality. Our findings show that this artery is solid and can be very useful in everyday cardiac surgical practice.
